I understand, im putting a lot of load on my machine doing backtesting, and my machine is an i7-6700HQ.....so it is more than 6 years old.
I suspect that the SSD is maxxed out because my RAM is maxxed out - my SSD has a 64GB paging file on it.
My question is two fold:
Is my paging file too big or too small?
Give that i have maxxed out my RAM and my Paging file, for my new laptop build does that mean that i need more than 64GB RAM?
Check the response time of your SSD IO's, tis is more relevant then the % of usage. If it's mode than 5 ms then your disk is really busy (or too full or dying).
About the swap: if you start to use swap the performance will be degraded. The good option, when you can, is to don't have any paging file, so you're sure to not using it.
64 GB of swap for 16 GB of RAM is huge, if your RAM usage is important Windows will spend most of its time paging in/out. It's better to have an crash for a RAM exhaustion problem, and then limit your RAM usage in your running apps, IMHO.
Am i not correct in assuming that since my RAM was 100%, then my machine would of crashed during backtesting.
I quite often get it to go to 100% utlisation.
I backtest 1 year for example, against 10 tickers and save best 25. The basically maxxes everything out.
I would actually backtest a longer period, with more tickers, but that's about the most the machine can handle.
